Problems solved by technology

However, the rounding combined jig needs to go through two processes and use a grinding wheel of a specific shape to grind a square workpiece into a circle. The two processes make the rounding time longer, and the grinding wheel of a specific shape needs to be customized, and the cost is high.

Embodiment Construction

[0012] Please refer to FIG. 1 and FIG. 2 , the rolling jig of the preferred embodiment of the present invention includes two opposing jig assemblies 10 , 12 . The two fixture assemblies 10 and 12 are respectively arranged on two sides of the workpiece 18 to be rounded. The workpiece 18 to be rounded is a non-circular optical lens, such as an infrared cut-off filter, etc., and the workpiece 18 to be rounded in this embodiment is square.

[0013] The fixture assembly 10 includes a connecting block 102 and a fixing table 104 . The connecting block 102 has a connecting end 1020 and a connecting shaft 1022 , and the connecting end 1020 and the connecting shaft 1022 are disposed on two ends of the connecting block 102 opposite to each other. The connecting end 1020 is used for fixedly connecting the workpiece 18 to be rounded, and the workpiece 18 can be fixedly connected to the connecting end 1020 by glue (such as ultraviolet glue) or other fixing mechanisms (such as claws). A be...

Abstract

A fixture of rounding machine for clamping several workpieces to be rounded is composed of oppositely arranged two clamping modules consisting of a fixing table and a connecting block installed onto said fixing table in rotary mode.

Description

【Technical field】 [0001] The invention relates to a fixture, in particular to a fixture required for rounding non-circular workpieces. 【Background technique】 [0002] In the optical industry, the optical workpiece is usually made into a circle, such as an infrared cut filter (Infrared cutting filter) of a digital camera and the like. However, the workpieces initially cut by industrial methods are generally square, so it is necessary to round the square workpieces to have rounded edges to meet optical applications. [0003] Cylindrical grinder is a machine used to process workpieces of various shapes into a circle. Its working principle is to use a high-speed rotating grinding wheel to grind the workpiece fixed by the grinding machine fixture to process it into a circle of the required size. shape. The general grinding machine fixing device is a pair of hollow fixtures. Firstly, the workpiece is adsorbed on one of the fixtures by using an air pump to suck air into the hollo...
